Specification of Letters Patent.

Patented Jan. 7, 1908.

Application filed August 8, 1906. Serial No. 329,739.

To all whom it may concern:

Be it known that 1, CHARLES E. Prnuonn, a citizen of the United States,residing at Evansville, in the county of Vanderburg and State ofIndiana, have invented certain new and useful Improvements in Pumps, ofwhich the following is a specification.

My invention relates to improvements in pumps, and refers in particularto the class known as chain pumps.

One object of my invention, is to provide suitable means for couplingthe chain pipe to the upper portion of the pump, and also the provisionof simple and effective means for preventing backward rotation of thesprocket wheel.

Further objects of the invention are the provision of means forstrengthening the sheet metal wheel box, and a detachable spout whichmay be readily attached or removed.

With these and other objects in view, my invention consists of a chainpump provided with a detachable spout, improved means for coupling thechain pipe to the base of the. pump, and means within the crank handlefor preventing backward rotation thereof.

The invention also consists of a pump cmbodying certain other novelfeatures of construction, combination and arrangement of partssubstantially as herein disclosed.

Figure 1, is a side elevation of my improved pump. Fig. 2, is a frontend view thereof, showing the chain pipe connected to the base. Fig. 3,is a central vertical sectional view through the wheel box and crankhandle showing the pawl in position therein. Fig. 1, is a detailsectional view of the coupling for securing the chain pipe to the base.Fig. 5, is a detail view partly in section of the pawl and ratchetmechanism on the crank handle. Fig. 6, is a bottom plan view of the pumpbase. Fig. 7, is a detail sectional view of a modified form of means forlocking the crank handle. Fig. 8, is another sectional view of the sametaken in a plane at right angles to the one in Fig. 7. Fig. 9, is anelevation of the wheel box with parts broken away to show the manner inwhich the lid is secured thereto.

In the drawings The numeral 1 designates the base of the pump preferablymade of sheet metal and formed with the inclined upper edges 2, and thecorner lugs or extension pieces 3. for anchoring the base firmly uponthe floor. Transverse cross bars 37, (see Fig. 6) are mounted in thelower portion of the base, and extending upward from the base, are thefront and rear chain pipes, 4 and 5,1'espectively, and supported upontheir upper ends, is the sheet metal wheel box 6. The wheel box isdivided into an upper and lower portion, the edge of the lower halfbeing provided with the strengthening wire or rod 7. At the properdistance above the base, the front chain pipe 4, is provided with anoutlet sleeve or collar 3, and a removable spout 9, is adapted to bemounted over this sleeve. The spout is formed with rearward extensionsor cars 10, and. through these cars a securing bolt 11, is passed sothat the spout is securely clamped to the pipe.

Secured by bolts 12, to the inner side of the wheel box, is the ournalbearing 13, and to the opposite side and exterior of the wheel box, isbolted the complementary bearing 14. This bearing 14, is formed with anexternal rim or extension 15, within which is confined the hollow heador collar us, on the end of the crank handle 17. 'lheinncr wall of thehollow head, is formed with corrugations or serrations 1S, and confinedwithin said head and pivoted to the journal bearing by means of the pin19, is a pawl 20, having the forked ends 21. The usual shaft or axle 22,carrying the regulation sprocket 7 wheel and chain (not shown) ismounted in the bearings and has the crank handle socured to one endthereof. As shown in Fig. 5, the forked pawl is adapted to lie to oneside of the shaft and engage the corrugations on the interior of thecrank head and thereby allow the crank to be rotated only in onedirection. The pawl may be arranged to allow rotation in eitherdirection by changing its position on either side of the shaft (shown indotted lines in Fig. 51.

The cover to the wheel box is adapted to rest upon the rim in the lowerhalf of the boxing, and at one side, the cover is formed with a lip 23,which engages under the wire rim, as shown in Fig. 9, and at theopposite edge is provided with a hooked spring tongue 24, which engagesthe rim and serves to lock the cover in place. The cover may be removedby inserting a nail or other sharp instrument in the opening 25,provided for that purpose and thereby releasing the tongue fromengagement with the rim.

The chain pipes may be secured Within the base by riveting or othersuitable fastening, and within the base is bolted an interiorly threadedsleeve 26, which makes tight oint with and extends a short distance uinto the front chain pipe. This sleeve is 'ormed at its upper end withan interior overhanging edge or rim 27. Into the sleeve 26, is screwed acoupling 28, within which closely fits the lower chain pipe 29, and whenthe coupling is screwed in place, the upper flanged end 30, of the chainpipe, is securely clamped between the overhanging rim and the end of thecoupling. The lower end of the chain pipe is provided with the usualflaring mouth 31.

In Figs. 7 and 8, is shown a modification of the means for locking thecrank handle. The bearing 14, is provided with the external circular rim322, but said rim is eccentric to the shaft, the lower edge of the rimbeing closer to the shaft than the upper edge thereof. The crank handleis provided with a flange 33,which entirely covers the annular rim onthe bearing, and it is further provided with a hub 34. A ball 35, isconfined within the space between the hub and the annular rim, and is ofa size sufficiently large that it cannot pass beneath the hub from oneside to the other. A lug or partition 36, extends downward from theupper portion of the rim and prevents the ball from passing from oneside to the other over the top of the hub. Thus it will be understoodthat the ball allows rotation of the hub and consequently the axle, onlyin one direction, and that it becomes wedged between the lower portion 1of the rim and the hub as soon as rotation is started in the wrongdirection.

From the foregoing description taken in connection with the drawings, itwill be evident that I have accomplished all the objects herein setforth, and have provided simple and efficient means for locking the]parts, which locking means are thoroughly protected from outsideinfluence.

I claim:

The pump herein shown and described comprising an open base havingcorner supporting lugs, transverse supporting bars extending across saidbase, chain pipes rising from and supported on said base, an internallythreaded sleeve secured to one of the transverse bars and having anupper overhanging rirn, a coupling engaged in said threaded sleeve, asupply pipe supported in the coupling having a lower flaring mouth and aflanged upper rim clamped between the upper end of the coupling and theoverhanging rim of the sleeve, the sleeve having its upper end extendingup into one of the chain pipes, an angularly outstanding outlet sleeveon one of the pipes, a spout fittin over said sleeve, the spout havingrearward y extending ears adapted to partly embrace the pipe, a clampingbolt secured between said ears, a divided wheel casing supported on thechain pipes, a brace rod surrounding the edge of the lower half of thecasing, the upper half of the casing having a depending hooked edge forengagement beneath the brace rod, a spring pressed catch depending fromthe opposite edge of the upper halffor interlocking engagement beneaththe brace rod, journal bearings carried by the lower half of the casing,a shaft supported in said bearings, a chain wheel and crank on saidshaft, and mechanism for preventing backward rotation of the shaft.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES E. PFENDER.
